The question was: Is it possible for a man in California to marry his widow's sister?

Analyzing the Question

The confusion in this question arises from its phrasing. Let's break it down:

• Widow: This term indicates that the man has died.
• Marry: A deceased person cannot marry anyone.

Common Misinterpretation

Many people, including myself, initially misread this question. It's easy to think that the question is about the man's wife dying, especially when skimming through the problem quickly.

Key Takeaway

This brain teaser is a great example of how easily we can misinterpret information when we don't pay close attention to the details. Always take the time to read and understand the full context of a problem before jumping to conclusions.
